i am doing A-level computing and for my project i need to be able to create a graph in a VB form using data imported from a spreadsheet at a given destination. I'm struggling to find any tutorials or posts that fit

I have a slight problem , using vb 2008 i have written some code that checks the current datetime on the computer. This gives me the answer in the format mon, tues etc. what i now want to do is to use that to call a spreadsheet dependent on the day of the week. here is my code so far
Code:
Dim TIME As DateTime = DateTime.Now
Dim FORMAT As String = " ddd "
TextBox1.Text = TIME.ToString(FORMAT)
[Code]....
Now i have tried the private sub eg SATS() on a separate button and it works perfectly . so it appears to be that the sub is not been called. I think it is probably a syntax where the datetime answer is not been recognised, in that textbox1.text = "sat" is not the same as datetime = sat .
I have a spreadsheet control on a windows form that I would like to populate with data from an existing worksheet (myworkbook.xls, sheet1).
View 4 RepliesI'm working on and add-in for Word 2003 that creates a custom toolbar when the add-in is loaded. However, most of the users will open documents through a file management system that uses automation to open the documents. I tried using the GetObject function to grab the instance of Word created through the automation but the toolbar isn't made visible (it only sits in the background and the users have to manually make the toolbar visible).
Code:
Public Sub createToolbar()

I have a website. In it, I have a button which will export some data from a SQL database to Excel. I want to open an excel workbook on the client and paste the data there. This all works fine locally, but when i publish it, I get this error:ActiveX component can't create object.[code]Have searched the net, and it seems the problem is permission related. Can anyone explain to me how to configure my server so that I can use clientside Excel?
View 2 RepliesI am not an expert programmer and am just getting familiar with .NET office automation. I have two questions:
1. For me to create word documents from my code on a server, does word have to be installed on the server? My test server does not have word installed. Is there a way to have the code open word on the user's machine in this case?
2. I am trying out some code for creating word documents. It works fine on my machine. However, when I try to run it on server it gives me an error.. "Cannot create ActiveX component." Is this a permissions issue or related to the fact that the server does not have word installed?

View 1 RepliesIt appears that when one creates an instance of Excel, using CreateObject, (Late binding), the suggested Excel closing function (with GC.collect etc) does not work. I have tried several suggestions, and the only one that works is process.kill method. Do you see any problem in using this? BTW: the reason we are using late binding is that we cannot use Office PIAs....not sure which version of Office would be installed on the client site. We work with O2003, but the client might still be at 2000 or 2002.

I'm trying to copy data from one workbook to another. The program first grab this data that comes in from a data collector and puts it in a excel spread sheet. It then closes its link to excel. I'm trying to grab that data out of the first spreadsheet and put it into a workbook thats set up like a template that will crunch the numbers. I'm currently dim-ing a varible called "grabber" as an Excel.range and setting it equal to the range of my raw data. Can I then say grabber.copy(Destination:=oWS.cells("A1")). I've been beating my head against a wall on this one.

Colum 3 is Sort Code and have the format 00-00-00, I want to change it to 000000 i.e., remove the dashes.
When exported to excel I use a formalue (Substitute(A1, "-", "") and this removes the dashes. But what I want to do is remove the dashes before exporting to excel... see the code below for datagrid - excel export, highlighted is where I think the one line code should be...

I am working with Vb.net and this code below works fine. However, when I review the data exported to excel I have a problem with one particular field i.e., sort code,( Columns (2) ) Sort code in the database it is in the format 00-00-00. Therefore if it is 12-11-09 or 11-01-66, a look alike of a valid date it is displayed as 12/11/2009 and 11/01/1966 in excel after the export. Excel thinks its a date which is incorrect. I expect it to show 12-11-09 and 11-01-66.

I have been trying to find a way to link VB .Net and excel in real-time. Using the COM and IRTDServer I have been able to send data from VB .Net to excel live (basic RTD server client), but I have not been able to find a way for the client to then publish back to the server real time, i.e. a cell that is changing based on a number of variable to be published back to the server and out to other clients real time.

I have written an automation addin in Excel with C# (addin.dll). To use the addin, I need to 1. register it using "regasm /codebase c:...addin.dll"2. select in ExcelOptionsAddInsExcel AddinsAutomation the respective addin from the list
I would like to automatize 1) and 2), so that the user just needs to run an exe-file in order to use the addin. 1) should be no problem, but how can one automatize 2)?
Ok basically what I need to do is the following:Read FirstExcelDoc (attached)For every row in that: Retrieve data from sql server db based on info in the Orange columns of FirstExcelDoc Let's say I retrieved data elements A, B, C, D, and E from sql server. Then I need to enter those same data elements A, B, and C in another excel spreadsheet (which has formulas etc) After inputing A, B, and C in that spreadsheet, read a couple of calculated fields and compare those results to data elements D and E retrieved originally from SQL Server DB. Finally, output the results in the Blue columns of the FirstExcelDoc spreadsheet for that row.Loop through and do the same thing for row 2 of the FirstExcelDoc and keep on until you see "END TEST" in the FirstExcelDoc.
I'm looking for a method of doing this efficiently. I have read several articles over the past few days as well as those from Mike R. but just need some direction to get started on this.To start of I'm looking for whether to read the entire FirstExcelDoc spreadsheet or just read the info for first policy number(2nd row) and process it and write out the blue column info for that row and then loop through and come back and read the second policy number (3rd row) etc... Please attach a code snippet for either way of reading the data.
I'm using excel via interop in application.Sometimes users kill application that created excel instance and that results in excel instance sitting in memory without any chance of disposing it.First I tried to tackle this using ROT(running object table) looks like not all instances of excel are registered there.Than I tried to somehow mark excel process after it is started via interop.[code]This works as long as excel is visible but in my case excel window is invisible.All I need is to somehow mark process that started via automation with the parent PID, so that later I can kill it if parent does not exist.

View 1 RepliesI have an Excel based algo-trading app that needs to take in lots of real-time data, and make trading decisions based on the calculations driven by the data. It is not one of those "read-only" stock ticker kinda spreadsheets.I created a COM object with VB.NET that runs in its own thread space which collects data from a socket, and when the data is read it raises an Event with data attached. In Excel VBA, the event handler parses the data, puts them to the right places on the spreadsheet to feed calculations (so far it sounds like a stock ticker app), and then, based on the results of the various calculations it does something.The problem is that when the user starts to click around the spreadsheet while there is large amount of data coming, the event handler's cell updating breaks apart. If the app is left alone without user action, it stands well. My frustration comes from not understanding what happens to the main thread when a user clicks around. Either the event handler blocks the user action, or the user action blocks the event handler (under which case I will put in some queuing facility). But I just don't see how user action can break the code (like causing VBA to stop executing)

We have a vb program which is run on our server by scheduled task every day. The program opens about 30 excel files, refreshes the data connections, pivot tables and then saves the document in another location.
This may run fine for a couple days but sooner or later the process starts crashing, usually with this error: RPC_E_SERVERFAULT.
My question is, Is it expected that continually opening/closing/refreshing workbooks will inevitably cause the Excel object to crash at some point.
i was wondering if someone could give me the final explanation on what i might be doing wrong here.I spent a lot of time reading around the net and the forum about how to add Threading capabilities to a VB project.
Nos, i've got .NET 4 installed, and i've added the system.tsr and mscorlib.dll files as reference in, say, Excel 2007 (see screenshot).However, when i try to make a thread with anything as basic as "Dim Thread1 As System.Threading.Thread", i get a user-defined type not found error.Indeed, when i use the object browser to see what's in the System file, theres nothing remotely linked to any Threading, and in the mscorlib file, nothing under "Threading" either, just a few Thread related functions, but nothing defining a data type
I've developed shared addin for Microsoft Word. I distribute this addin with my application and using Inno setup for installation. The Inno setup installs my application and then runs "myAddin.msi" file in order to install addin.
how to uninstall this addin programatically?
Right now, in order to uninstall addin, the user has to to it manually through control panel.
